Abstract: To provide with an effective method for non-photorealistic rendering for computer generated images with artistic appearances from 2D images motivates our work in this paper. The methods proposed in this paper are inspired by the many pieces synthesis mosaic effects. In this paper, we mainly propose the method for generating the artistic appearances based on the pieces synthesis and color tranfer technique. The block pieces can be chosen from arbitrary quantity images in the database. First, to accelerate synthesis speed, the mosaic effect can be generated based on the luminance channel. Further, we establish our method for obtaining RGB appearances taking the color transfer as the underlying basis. Therefore, the color of input image can be rendered to the final mosaic artistic effects. Experimental results show that our methods are effective and efficient.

Abstract: To the problem of memory consumption caused by the method based on GPU geometric segments, this paper used the new features of DX11 inlaid the PN-Patch geometric segmentation to resolve. Mixed triangular and quadrilateral mesh, combined with displacement maps and normal maps to get rich surface details with reasonable viewpoint mosaic factor calculation method.

Abstract: The virus-induced mosaic Camellia reticulata cultivars in southwest China were identified, and evaluated for their ornamental value and bio-security in landscape. The results show that 11 virus-induced mosaic Camellia reticulata cultivars are found. The virus in mosaic leaves is spherical, with 30-50 nm in diameter. For the mosaic leaves, the chloroplasts are degraded in the yellow macular region, and the content of chlorophyll is significantly decreased. However, the virus-induced mosaic Camellia reticulata grow normally, and with significantly improved of visual appeal due to mosaic leaves. Further, the virus-induced mosaic Camellia reticulata have no bio-security threats to the main crops and other landscape plants. Thus, the virus-induced mosaic Camellia reticulata can be cultivated normally in the landscape in southwest China.

Abstract: This passage proposes a new method to detect mosaic not only using the Y (luminance) component in YUV color space of videos, but also using the U (chrominance) and V component. The mosaic effect is measured by the boundary pixel difference from the neighbor macroblock. Instead of detecting the existence and position of mosaic blocks as traditional methods do, this method focuses on the statistics of the number of suspected mosaic blocks so that the quality of the whole frame affected by mosaic can be assessed. Experimental results show that the new method has good performance on fallout ratio, omission factor and computational complexity.

Abstract: Funeral building environment is part of the ecological system, it undertakes important duties like human burial, urban cultural landscape and tourism, and urban development. Funeral building environment landscape as patch design is the important tache of space landscape construction and development. It should aim at restoring local ecological environment, providing city environmental services, and helping to recover ecosystem and biodiversity that have been destroyed. It will repair the damages like biological component damage caused by urbanization, natural biological communities and species declining and urban ecological system stability destruction, so as to promote the development of funeral building ecological environment, and create a development environment with man and nature in perfect harmony.
